It is n'lever 31 fulc est e t icing e in i t n e y mentioned.The lever is provided with three ea o 4: s e i n and 3'cooperaterespectively with a piece of the framinglprtnridecl with two actingpoints, 35 and-36. "Wlii sntheplate 11 is in its porn a'l or lowerposition, then the parts are as shown in Fig. 2; namely 32 is below andsomewhat to the from: (if v35, and 33 is 5Q below and somewhat to theback of 36. As

soon astheplate commences to rise the presence of 35 causes 32 to moretoward the heck while 33 swin s to the front nst over fi. Upon \thfurther rise of the p ate 11, 32 continues to be in contact with its .00

operating port and the lever 31 thus remains in its operated position.The swing of the lever ubout its fulcrum has the effect of swinging hook34 to the front. Said hoolc thus engages the top of the universal be r20 and remains so engaged for the rest of the rise of the plate 11, anddoes not disengage until said plate has resumed its normal lou'uiposition Since the initiating of :1 cycle oi the universal bar 20 willnot permit it to re Tofiielp' accomplish this urpose the turn until saidcycle has been completely moved through, and since by the mechanism justdescribed. the initiating f'a cycle of a key lever ittosaid'unitersalfbar and retains said look through saidicycl'e'until thecompletion thereof, it is evident that any key lever is also compelledto finish its cycle onceithas been initiated. i

The digiting mechanism of this machine -wi-l-l' now be described. lt -iscomposed of a set of digit pins 40 and cooperating mechanism. Thedepressing of any numeral. he protrudes its own di 't pin 'to'bc furtheroperated upon. Eac digit pin 40 issuported at its front in the flamingand-at its back is pivoted to the up per'portion ofa lever 41. All thelevers 41 are fulommod upon a shaft 42. Each lever 41 is prbfwtided withtwo acting points 43 and i l, cooperatmg respectively with the bevels 15and 16,

previously mentioned as being" artof the plate 11. An examination of 2shows that the raising of the plate causes the'protrusion of digit: in 40-which protrusion-lasts through thej-w ole cycle of upward'aud downwardmovenient'of the plate and-tl1a thecligit pinisnot withdrawnto itsnormal position until the plate has again reached its normal position.

The angle having its vertex at51 and whose two sides extend through the centers of the pins 48 and 49,thus becomes a cqnstunt angle in this particular case,-'a strai 'htangle.

V This isaccomplishedthrough theintermediation of links 78, levers 79 and cams 80 and 81. The cams areso shaped that upon the rotation of the shaft 23, first the framing 77is raised until the master wheels andsthe pinions engage the totalizercarrying pinionsy-simultaneously the gearafi'? engages the gear 52. Theframetlien remains in its liftedIposition-while the further rotationof-the cycle shaft, causes tfhe digital .movemeut, of the gear 57, thusalso ofthe' master-Wheels, and ,,alSO gQf the t'otalizerh gears.MSubseqnent, to tl e cessation 'of this digital movementthe t-fr ame ,islowered to ,unmesh all. the gears meshed by raising.- L flh en the gear52 g is, brought back to its-normal positiouby th e' lowering to itsnormal position by,.the ,loweringito its'normal; position of-the tilt-,able pieee5Q. l 9; Eaeh-totalizeris provided with a locking bar 82,,,fulcrumed .in the-v walls thereof. at 83 and provided With a sprin 8thtending ",toholdfthe'gears; locked.

Each locking barjSprovided with a link 87 anch-a lever;88 ;which cooperates-with two catns8 9 and; 90, jupon the cycle, shaft. The camsareYso-shaped, that theirleigers-all :open their looking barssimulta'neously, but close theirlocking bars successively. Theilocking bar at: the right closes-first,the one adjacent to it at-therleft,-next, etc. This overcomes theinaccuracy of movement in the yer-ions totalizer carrying pinions and;transfer pini'onsas they are alined successively going from right-toleft.

The action "of the cams controlling the locking bars 85 may be describedin greater detail in-connection with Figure 8, inwhich fig-urea single'pair of cams 89 and 90 are shown. It will be remembered that these cams89 and 90 are rigid on the cycle shaft il, and that said shaft makes onecomplete revolution in a counter clockwise direction each time'a.numeral key is operated. The lever 88 has mounted thereon the tworollers 100 and 101, which co-operate with the cams 89 and 90respectively.

'iReference to cam 89 will show that it is provided with a liftingsurface 104 and a drop 102. Reference to cam 90 .willshow that it isprovided with a drop 105 which co-operateswith the roller 101 simultanefouslyiwvith -.the action of the suriace 104 .onwthei roller 100, and alifting surface 103 which cooperates with the roller 101 simul'taneously -.with :the dro 102 on cam 89, co operating with the -r.o ler100. Therefore each revolution of .the cyele shaft will first rockthe'lever 88 in a clockwise direction,

@structed that a,,determined motion being termined' bythe angle betweenthe surfaces cams shown in Figure 8 are those which 9 eratethe lockingbar 85 immediately to t e left of the master wheel, the next pair"oflcams 89 and 90'operating the next lever "881:0 the leftwould havetheir surfaces 104 8. However, the surfaces 102 and 103 would'- and 105in line with the surfaces 104 and 105 of the pair of cams shown inEigure be displaced in a clockwise direction so as -to make the anglebetween the surface 10 and 102 of said higher order cams greater thanthat shown in'the cams illustrated in Figure 8. "A cam of still higherorder would have the angle 104,23-102 still greater, so that therotation of the cycle shaft 23 would 7 result first in all the levers 88being-rotated in a clockwise direction simultaneously, and then in'therestoration of these levers 88 one after the other, beginning with thelever immediately to the left of the master wheel.

It is well-known that the spiral occurring when the totalizer carriesthrough all its orders can be corrected by first correcting the error ofthe wheel immediately adjacent to the master wheel, and then bycorrecting the error of wheels in higher order. It is evident that withthe arrangement of cams as above described this result will be obtained.

The link 87 has been introduced to allow the raising of the locking bar85. Such raising occurs because it is mounted in the framing 77.

The operation of the parts is as follows: First the framing 77 is raisedto engage the totalizer; then the locking bars are opened, the lockinbar 85 opening the locking bar 82; then tie digital movement occurs;then the locking bars are closed; then the train ing 77 is lowered; andfinally the digiting gear 52 is brought back to its normal position.

Lao rem Attention is called to the fact .that the left side wall of thetotalizer is provided with downhanging teeth in alinement with the teethof the carryin .gears in their normal position. When tie framework 77 israised and the master wheel and the transfer .iwould :beimparted/thereto only by friction from ,thoseto-the right, and therightmost io1; these totalizer ear-noncontrolled-pinions is nowheldlockeg.

I-n someiofsthe claims of this case I have used. theexpression5:constant aggregate motion linkage. .By this, I mean a mechanism,having'three points offreedomgind so congiven to .onccf these points,there results --motion :of the second .and third points, and

the sum of the motions of the second and third points is a constant. Alinkage of this kind is admirablyadapted for transforming a constantmotion of the source into a differs =eutiated movement .ofone of thepoints of freedom, and this differential motion may be had without the.use of springs since it isonly necessaryato..arra-nge the second andthird points that their. motions will be towards .each,other andinterpose an immovable piece between Ithem. This linkage may be arrangedin :a variety of ways. I have disclosed one conven-ient'iorm in thisspecification. Another example would be an epicyclic gear movement morecommonly known as a differential gear. lt -will, be remembered that ifone gives a certain motion to the center mem- .ber of a differential theresulting motion mavoccur all on one side, or part on one side and parton the other side, but in any event the sum of the resulting motions ofthe sides .will be a constant. Another example of a link motion of thiskind is given in my copendin application, Serial Number 697,704, fileday 16th, 1912.

The use of a linkage of this kind in a calculating machine for producingdifferential motion of the master mechanism offers pecu liar advantagessince such difi'erential mo-. tion may be produced without springs ofany kind. Each key has a member which may be thrust in the path of thelinkage. and a universal member moved by any of the digit keys willclose the linkage by such protruded piece. I believe I am the first toshow a linkage of this kind in combination with the master mechanism,and wish to cover same broadly.

Many changes may be made in the precise uncchamsm form and constructionof the device herein shown without departing from the spirit of myinvention. I
